Product Description V-Type Compressors A V-type compressor is a typical structure of reciprocating compressors, where cylinders are symmetrically arranged at a V-shaped angle (usually 60° or 90°). It drives the piston to move reciprocally through a crankshaft connecting rod mechanism to achieve gas compression. The following analysis covers technical characteristics, application scenarios, industry trends, and maintenance key points: I. Core Technical Characteristics 1. Structural Design - V-shaped Cylinder Layout: Cylinders are typically angled at 90° (optimal balance) or 60° (more compact structure), with two cylinders sharing the same crankpin and moving synchronously via connecting rods. - Dynamic Balance Optimization: Inertial forces are counteracted by additional balance weights to reduce vibration (e.g., 60° angle models can balance first-order reciprocating inertial forces), making them suitable for foundation-free installations. - Lightweight Design: For example, GMCC's "V-Zhineng" compressor uses a large rotor + V-shaped magnet motor, reducing volume by 50% and improving energy efficiency by 9%. 2. Working Principle - Four-Stroke Cycle: Inhalation → Compression → Exhaust → Expansion, achieving gas compression by changing cylinder volume through piston reciprocation. - Key Components: - Crankshaft Connecting Rod Mechanism: Converts motor rotational motion into linear piston motion, requiring high-precision machining to minimize wear. - Valve System: Uses sector-shaped valve plates or streamlined balance weights to reduce airflow resistance and improve efficiency. - Lubrication and Cooling: Splash or pressure lubrication systems ensure the service life of moving parts; air or water cooling designs adapt to different environments. 3. Energy Efficiency and Environmental Protection - Inverter Technology: GMCC's independent compression technology increases air conditioner APF (Annual Performance Factor) by 10%, significantly optimizing heating performance at low temperatures. - Heavy Rare Earth-Free Motors: China Household Electrical Appliances Research Institute has developed inverter compressors without heavy rare earths, reducing rare earth dependence and enhancing system energy efficiency. II. Application Fields 1. Industrial Sector - Petrochemical and Natural Gas: High-pressure V-type compressors are used for natural gas transportation and hydrogen refueling stations (e.g., Kaishan Group's V-series high-pressure reciprocating compressors with a discharge pressure of up to 400 Bar). - Marine Power: Their compact design fits ship space, providing stable gas sources for deck equipment and...
